"A car bomb was detonated by an unidentified attacker outside Budizirah Park near the city’s eastern entrance," Interior Ministry spokesman Walid al-Orfi told Anadolu Agency.
"While no one was killed, at least 15 passersby were injured by the blast," al-Orfi said.
"Security forces have since cordoned off the blast site and launched an investigation into the attack," he added.
No group has claimed responsibility for Tuesday’s bombing.
On Oct. 30, a similar car bomb attack in Benghazi left three people dead -- including a political activist -- and another 21 injured.
Libya has remained in a state of turmoil since 2011, when a bloody uprising ended with the ouster and death of longtime strongman Muammar Gaddafi.
